Homeboy2 :
Exactly why do you need TWO 5870's? Do you have a 30" monitor or is that 700 bucks burning a hole in your pocket? Buy one now and wait till prices go down to buy the second. Maybe by that time games might need it.Other wise you're just wasting your money unless you wanna be the local benchmark king.
This.
I cannot think of a single case in the history of computers where, if you buy the most powerful graphics card currently available, it will do anything less than operate every game perfectly, as well as any game that comes out for the next year or two. Buying a second card makes no appreciable difference unless you're more hung up on your technical specs than on actually enjoying the fricking game.
Honestly, my most recent machine is a Q9550 with a single HD4870 ... and while that's about a year removed from being cutting-edge, it's more than enough to run anything I want, and it still blows the mind of anyone who's not a gearhead.
I honestly think a lot of questions like this are people who somebody bought them an Alienware system for their birthday and now they don't know what to do with it, but they think they ought to be doing SOMEthing. No. Just enjoy the fact that you have a great system for a year or two, and
THEN worry about doing open-heart surgery on it.
I am not directing that at the OP in this thread becuase I really have no idea what his situation is, but I've seen a lot of it on various forums like this.
